Balancing reactions (p17)
Steps:1. Write element list underneath arrow.2. Take atom inventory on each side of arrow3. Use multipliers (coefficients) to balance elements. Balance H second to last and O last. If you struggle to balance and are left with ONLY O, double all your coefficients.

2. ____Pb(NO3)2+ ____HCl → ____PbCl2 + ____HNO3
3. ____BaO2 → ____ BaO + ____O2
Rotation Stations Groups of 4-5
Start at a station and complete ONE step of writing and balancing the reaction as a group
When you rotate you will check the previous steps, fix anything that is wrong and complete the next step.
The final station you land on will you YOUR groups and will be graded on ACCURACY.
